Feet Up Friday - Thank God for Bob! //Discussing the latest F1 launches plus all the news from Mercedes

Feet Up Friday returns for the first time in 2013, to take a comprehensive look at the team and tyre launches plus the neverending news from Mercedes.

We discuss Eddie Jordan's latest scoop and the fact it has yet to come to fruition, plus how Williams and Mercedes have both been affected by Toto Wolff's big move. We ponder the concept of tyre launches and whether it is over the top for the round rubber to get their own press day.

Finally, we run through the launches - both in terms of presentation and the car that was revealed - plus more on watching F1 in the UK, and some tweaks on Twitter.
